Title: MATERIAL SAMPLE, METHOD FOR ESTABLISHING A SAMPLE GEOMETRY, METHOD FOR DETERMINING A MATERIAL BEHAVIOUR AND/OR MATERIAL CHARACTERISTIC VALUES, STRESS-STRAIN CURVE OF A MATERIAL AND PRODUCT
Abstract:
The invention relates to: a material sample (100) for determining a material behaviour and/or material characteristic values in a load test, characterised in that the material sample (100) has a plastically deformable main deformation section (108), an elastically deformable deformation section (112) and a plastically deformable auxiliary deformation section (114), wherein the main deformation section (108), the elastically deformable deformation section (112) and the auxiliary deformation section (114) are coordinated with one another taking into consideration a sample material, a material dimension, a measuring method and/or a load speed, in order to permit a vibration-reduced determining of deformation forces even with high strain rates; a method for establishing a sample geometry of a material sample (100) of this type; a method for determining a material behaviour and/or material characteristic values in a load test using a material sample (100) of this type; a stress-strain curve of a material, wherein the stress-strain curve is determined using a material sample of this type; and a product, wherein the product is designed using material characteristic values, which were determined using a material sample of this type.
